Vacuum hoses & emissions

I am wondering which vacuum hoses are absolutely necessary for the engine to run with a motorcraft 2100 carb. I don't need to worry about emissions so I am really curious again what vac hoses are really necessary. Any answers are appreciated. Thank you.

Yup, that's all you need to run. Just make sure you cap off any unused vacuum sources at the carb/intake so you don't have a vacuum leak.
